# APIs-Google

> Delivers push notifications for Google APIs to a webhook you registered. It is a special-case crawler: it ignores the robots.txt * group, because the fetch is a delivery to an address you asked it to deliver to.

## What blocking it costs you

Google API push notifications stop arriving at your endpoint. This only affects services you set up yourself; there is no search or AI consequence.

## Ask this page a question, with one GET

A question about this page, answered by a call you can make right now — no key, no account, no JSON-RPC, nothing to assemble. The query string is already filled in with this page's own subject.

- **How do I prove a request really is APIs-Google?**  
  `curl -s 'https://www.pathwren.workers.dev/tools/verification-methods?crawler=apis-google&s=client-dossiers'`  
  The verification method its operator actually publishes — published IP ranges, reverse DNS, or nothing at all — and the mirror of it on this host.
- **Is 108.177.2.0 really APIs-Google?**  
  `curl -s 'https://www.pathwren.workers.dev/tools/verify-crawler?ip=108.177.2.0&ua=APIs-Google&s=client-dossiers'`  
  That address checked against every prefix this host mirrors. 108.177.2.0 is the first address of 108.177.2.0/27, one of the ranges listed on this page — so the link is a worked example that returns a match. Swap in an address from your own log.

Every parameter above is a value the endpoint reads, not an address it visits: nothing is fetched on your behalf. Called without any parameter, each endpoint returns its own specification instead of an error.
